' Application filed January 25, 1907. Serial No. 354,076.

To all'wlwm it may concern." j

Be it known that I, J Es'MoCAB citizen of the United States, residing atMinneapolis,

- in, the county of Hennepin and State of Min' 7 Qnesota,

have invented a new and useful Load- Alfipparatus, of'whioh thefollowing is' a c cation. i

This invention relates to a loading apparatus'of that type em loying aforwardly extending gathering ork that is pivotally mounted on itsvehicle so as to be actuated by;means' vof the forward movement of thelatter through suitable manually controlled mechanism. arranged betweenthe fork and one of the Wheels of the vehicle, and it l e-4 lates moreparticularly. to a loading apparams in which the fork is adapted toeposit its contents into a suitable box or receptacle carried by thevehicle at the rear of the fork.

: The invention has for one of its objects to rovide an apparatus forloading shocks of ay, grain, fodder, or other material, into "the bodyofthe vehicle in'a simple, convenient and effective manner.

I vision of a pivotally mounted gatherin ork A further object of theinventionis the rowhich is actuated by means of a flexible ele- 'ment,arranged to simultaneously wind at one end and unwind at the other endon oscillatory quadrant or sheave segments, one quadrant or sheavesegment being-actuated from one of the axles of the vehicle through agearing that is adapted to be clutched and unclutched by the attendant.

Another object is the employment of a buffer arranged on the frontendofthe vehicle box or body. in thepathof the fork so as to cushion thelatter at the end of its lifting stroke.

A further object is to improve and simplify the construction andoperation of apparatus of the character referred to so as to becomaratively simple and inexpensive to manuacture and keep in repair,

manipulate.

ith these, objects in view, and others, as will appear as the nature ofthe invention is better understood, the invention comprises features ofconstruction and arrangement of. parts, which will be more, fully?described hereinafter and set forth Withparticularity in the claimsappende'dhe'reto, Iii the accompanying drawing, whlch illustrates one ofthe embodiments of the invenf axle 4 for the rear Wheels.

' Referring to the running gears of a which is pivotally mounted atilting box or body B, and hingedly supported on the running gear at apoint in front of the box is agear comgathering fork C. The runningprises front and rear supporting wheels 1 and 2 on'which the frame 3 iscarried. The tilting box is of that type having its axis of tiltingslightly to the rear of its middle so that'the forward portion of thebox will rest normally on the frame 3 while'the rear portion overhangsthe latter, the axis of tilting being the prises a plurality of paralleltines 5 suitably connected together and pivoted at their rear .80

ends on the shaft 6, the said shaft-being journaled in bearings 7 (ofwhich one is shown in the present illustration) and located slightly inadvance of the front end of the box 3. Carried on the front of the boxis a bufier D comprising a frame 8 pivoted at its bottom to the box B atthe point 9. This frame is yieldingly held in a forwardly in-i clinedposition 'by means of the extension spring 10 located under the box withits rear end 11 anchored thereto and its front end connected'to theframe 8. The bufier D is thus located in the path of the fork C as itmoves on its lifting stroke, thereby cushion ing the latter and bringingit gradually to rest without striking forcibly against, the box B Themechanism for actuating the fork C is constructed asfollows :-Adjacentthe front of the frame 3 of the vehicle is a sheave seg ment or quadrant12 fulcruined at l3 on the frame 3 at a point slightly in front of thebox B. This sheave segment or quadrant cross section, said member 15connected. 1s disposed normally 1n a The fork C com-,

This sheave segment or quadrant is composed of acurved metal strip 19 of.V-

when the power is released from the actuatmg sheave segment or quadrant18 The cam 18 is mounted on the rear axle 4 and is adapted to beclutched thereto when the op erator desires to raise the fork. The clutcing'and unclutching ofthe sheave segmentor quadrant with the axle isaccomplished by means of a gear constructed on the compensating type andcomprising a wheel 2'2 Keyed t0 the rearaxle 4 and carrying a pluralityof pinions 29 that mesh with the teeth on the wheels 24 and 30, whichlatter are loosely amounted on the axle. To cause the sheave segment orquadrant 18- to be actuated, it is merely necessary to arrest themovement of the wheel 30. This causes the pinions 29 to actuate thewheel 24 forming part of the cam structure 18. To. arrest the movementof the wheel'30, the latter is provided with a plurality of radiallyextending projections 31, and mounted'on the frame 3 adjacent thewheelisa lever or stop 32 fulcrumed at 33 and carrying'a roller 34 thatis adapted to engage .the periphery of the wheel 30 and abut any one ofthe projections 31. This stopdevice 32 isconnected by the rod 35 tothe'operatin'g lever 36fulcrumed adjacent the front of the frame 3.

From the foregoing description, taken in connection with theaccompanying drawing,

the advantages ofthe'construction and of the method of o eration Willbereadily apparent to those'skil ed in the art to which the inventionappertains.

- Assuming that the fork C has received its load, and the attendant hasthrown the lever 36 forwardly, the fork is raised in the followe ingmanner. I The stop 32is-moved from its dotted line position, Fig. 2, toits full line position through the movement of the opermally' rotateswith I the axle 4 -by-; meshing with the inions 29, is immediatelybrought to. rest so t atthe .1wheel 24 of thesheave seg ment' orquadrant-18, whichhas in the meantime .beenidle', is actuated by thepinions 29 ating lever '36. The wheel 30,1 which nor a which revolvewith the wheel 28. The

sheave segment or quadrant 18 is thus turned so as to cause the cable 26to wind thereon w and unwind from the sheave segment or quadrant 21.Since -the said cat is con-..

nected with thefork C, the latter is raised so as to deposit its loadinto the box B. Near the end of the unloading stroke, the forkstrikesagainst the buffer B so as to permit the stroke to end gradually.As soon as the material on the fork is deposited, the oper-- atorreleases the lever 36 so that the fork can return to its normalposition. As the fork swings down, the cab e 26 winds up on the sheavesegment or quadrant 12 and upwinds from the sheave segment or quadrant18'.

By releasing the lever 36, the wheel 30 is free to turnduring-the returnstroke of the sheave r segment or quadrant 18.
